| 1 | Plant abiotic stress response and nutrient use efficiency显示文摘Abiotic stresses and soil nutrient limitations are major environmental conditions that reduce plant growth,productivity and quality.Plants have evolved mechanisms to perceive these environmental challenges,transmit the stress signals within cells as well as between cells and tissues,and make appropriate adjustments in their growth and development in order to survive and reproduce.In recent years,significant progress has been made on many fronts of the stress signaling research,particularly in understanding the downstream signaling events that culminate at the activation of stress-and nutrient limitation-responsive genes,cellular ion homeostasis,and growth adjustment.However,the revelation of the early events of stress signaling,particularly the identification of primary stress sensors,still lags behind.In this review,we summarize recent work on the genetic and molecular mechanisms of plant abiotic stress and nutrient limitation sensing and signaling and discuss new directions for future studies. | Zhizhong Gong Liming Xiong Huazhong Shi Shuhua Yang Luis R.Herrera-Estrella Guohua Xu Dai-Yin Chao Jingrui Li Peng-Yun Wang Feng Qin Jigang Li Yanglin Ding Yiting Shi Yu Wang Yongqing Yang Yan Guo Jian-Kang Zhu | 2020 | Science China(Life Sciences)2020，63，5： | 94 |
| 2 | Molecular Regulation of Plant Responses to Environmental Temperatures显示文摘Temperature is a key factor governing the growth and development,distribution,and seasonal behavior of plants.The entireplant life cycle is affected by environmental temperatures.Plants grow rapidly and exhibit specific changes in morphology under mild average temperature conditions,a response termed thermomorphogenesis.When exposed to chilling or moist chilling low temperatures,flowering or seed germination is accelerated in some plant species;these processes are known as vernalization and cold stratification,respectively.Interestingly,once many temperate plants are exposed to chilling temperatures for some time,they can acquire the ability to resist freezing stress,a process termed cold acclimation.In the face of global climate change,heat stress has emerged as a frequent challenge,which adversely affects plant growth and development.In this review,we summarize and discuss recent progress in dissecting them olecular mechanism sregulating plant thermomorphogenesis,vernalization,and responses to extreme temperatures.We also discuss the remaining issues that are crucial for understanding the interactions between plants and temperature. | Yanglin Ding Yiting Shi Shuhua Yang | 2020 | Molecular Plant2020，13，4： | 40 |
| 3 | AP2/ERF转录因子调控植物非生物胁迫响应研究进展显示文摘低温、干旱、高盐和缺氧等多种不良环境影响植物的生长发育,植物通过长期进化形成复杂的调节机制来适应这些不利条件。AP2/ERF是植物特有的转录因子,在各种胁迫响应过程中发挥关键调控作用。近年来,越来越多的研究表明,植物激素介导的信号级联通路与逆境胁迫响应关系密切,AP2/ERF转录因子可与激素信号转导协同形成交叉调控网络。许多AP2/ERF转录因子通过响应植物激素脱落酸和乙烯,激活依赖或不依赖于脱落酸和乙烯的胁迫响应基因的表达。此外,AP2/ERF转录因子参与赤霉素、细胞分裂素和油菜素内酯介导的生长发育和胁迫应答。该文简要综述了AP2/ERF转录因子的结构特征、转录调控、翻译后修饰、结合位点、协同互作蛋白及其参与调控依赖或不依赖激素信号转导途径的非生物胁迫响应研究进展,为解析不同AP2/ERF转录因子在调控激素和胁迫响应网络中的作用提供理论依据。 | 洪林 杨蕾 杨海健 王武 | 2020 | 植物学报2020，55，4： | 20 |
| 4 | Rice functional genomics:decades'efforts and roads ahead显示文摘Rice(Oryza sativa L.)is one of the most important crops in the world.Since the completion of rice reference genome sequences,tremendous progress has been achieved in understanding the molecular mechanisms on various rice traits and dissecting the underlying regulatory networks.In this review,we summarize the research progress of rice biology over past decades,including omics,genome-wide association study,phytohormone action,nutrient use,biotic and abiotic responses,photoperiodic flowering,and reproductive development(fertility and sterility).For the roads ahead,cutting-edge technologies such as new genomics methods,high-throughput phenotyping platforms,precise genome-editing tools,environmental microbiome optimization,and synthetic methods will further extend our understanding of unsolved molecular biology questions in rice,and facilitate integrations of the knowledge for agricultural applications. | Rongzhi Chen Yiwen Deng Yanglin Ding Jingxin Guo Jie Qiu Bing Wang Changsheng Wang Yongyao Xie Zhihua Zhang Jiaxin Chen Letian Chen Chengcai Chu Guangcun He Zuhua He Xuehui Huang Yongzhong Xing Shuhua Yang Daoxin Xie Yaoguang Liu Jiayang Li | 2022 | Science China(Life Sciences)2022，65，1： | 12 |
| 5 | 植物抗氧化动态平衡研究进展显示文摘植物在生长发育的过程中会产生代谢副产物活性氧,其含量在植物生长过程中起双重作用。适量的活性氧可提高植物对逆境胁迫的耐受性,但是过量的活性氧会诱发氧化猝发反应,严重影响植物的生长发育。因此,提高植物的抗氧化能力对于提高植物的抗逆能力来说显得尤为重要,该方面的研究也成为近年来逆境生物学的一大热点。植物体为了应对逆境环境造成的活性氧动态失衡,进化出了含酶和非酶组分的抗氧化系统。本文主要介绍了参与高等植物活性氧代谢的相关物质,对近年来国内外报道的代谢途径进行了综述,为提高植物的抗逆能力提供参考依据。 | 高媛 薛艳红 刘士平 | 2019 | 生物资源2019，41，1： | 12 |

| 10 | Shaping polyploid wheat for success:Origins,domestication,and the genetic improvement of agronomic traits显示文摘Bread wheat(Triticum aestivum L.,AABBDD,2 n=6 x=42),which accounts for most of the cultivated wheat crop worldwide,is a typical allohexaploid with a genome derived from three diploid wild ancestors.Bread wheat arose and evolved via two sequential allopolyploidization events and was further polished through multiple steps of domestication.Today,cultivated allohexaploid bread wheat has numerous advantageous traits,including adaptive plasticity,favorable yield traits,and extended end-use quality,which have enabled its cultivation well beyond the ranges of its tetraploid and diploid progenitors to become a global staple food crop.In the past decade,rapid advances in wheat genomic research have considerably accelerated our understanding of the bases for the shaping of complex agronomic traits in this polyploid crop.Here,we summarize recent advances in characterizing major genetic factors underlying the origin,evolution,and improvement of polyploid wheats.We end with a brief discussion of the future prospects for the design of gene cloning strategies and modern wheat breeding. | Jie Liu Yingyin Yao Mingming Xin Huiru Peng Zhongfu Ni Qixin Sun | 2022 | Journal of Integrative Plant Biology2022，64，2： | 5 |
| 11 | Rheostatic Control of ABA Signaling through HOS15-Mediated OST1 Degradation显示文摘Dehydrating stresses trigger the accumulation of abscisic acid(ABA),a key plant stress-signaling hormone that activates Snf1-Related Kinases(SnRK2s)to mount adaptive responses.However,the regulatory circuits that terminate the SnRK2s signal relay after acclimation or post-stress conditions remain to be defined.Here,we show that the desensitization of the ABA signal is achieved by the regulation of OST1(SnRK2.6)protein stability via the E3-ubiquitin ligase HOS15.Upon ABA signal,HOS15-induced degradation of OST1 is inhibited and stabilized OST1 promotes the stress response.When the ABA signal terminates,protein phosphatases ABI1/2 promote rapid degradation of OST1 via HOS15.Notably,we found that even in the presence of ABA,OST1 levels are also depleted within hours of ABA signal onset.The unexpected dynamics of OST1 abundance are then resolved by systematic mathematical modeling,demonstrating a desensitizing feedback loop by which OST1-induced upregulation of ABI1/2 leads to the degradation of OST1.This model illustrates the complex rheostat dynamics underlying the ABA-induced stress response and desensitization. | Akhtar Ali Jae Kyoung Kim Masood Jan Haris Ali Khan Irfan Ullah Khan Mingzhe Shen Junghoon Park Chae Jin Lim Shah Hussain Dongwon Baek Kai Wang Woo Sik Chung Vicente Rubio Sang Yeol Lee Zhizhong Gong Woe Yeon Kim Ray ABressan Jose MPardo Dae-Jin Yun | 2019 | Molecular Plant2019，12，11： | 5 |
| 12 | 水分及高温环境胁迫对薄荷幼苗活性氧代谢与总黄酮累积的影响显示文摘水资源紧缺和全球气候变暖趋势,使药用植物同时面临着水分及高温胁迫.本文以薄荷幼苗为研究对象,通过光照培养箱模拟胁迫环境,用聚乙二醇(PEG6000)模拟水分单一胁迫,设置40℃为高温单一胁迫,二者交互为复合胁迫,蒸馏水、25℃为对照,主要测定0~24 h超氧阴离子(O2-^-)产生速率,超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性,过氧化氢(H2O2)、丙二醛(MDA)质量摩尔浓度,以及黄酮的质量分数变化.结果显示:水分及高温单一、复合胁迫处理下,O2-^-产生速率、H2O2质量摩尔浓度、SOD、POD和CAT活性表现为先升后降的趋势,单一胁迫MDA质量摩尔浓度为整体上升趋势,复合胁迫MDA先升高后降低;4~12 h之间,复合胁迫各检测值显著高于单一胁迫,表现为协同效应;24 h复合胁迫下所有检测值先于单一胁迫降低至(甚至低于)对照水平.可能是由于复合胁迫伤害大于单一胁迫伤害,随着时间的延长,率先突破薄荷幼苗忍受临界点导致死亡.黄酮累积的变化表现为从4 h上升至8 h质量分数最大,到12 h显著下降,与O2-^-产生速率、H2O2的质量摩尔浓度分别在4、8 h达到最大,到12 h显著降低的趋势一致,提示胁迫条件下黄酮的累积很有可能是因为活性氧的产生而上调的.研究表明:水分、高温胁迫可以通过诱导抗氧化酶来保护薄荷幼苗因活性氧的产生而导致的伤害,但是有限的;活性氧同时又可能提升幼苗黄酮的累积.因此,在实际生产应用中,不仅要考虑到胁迫的协同效应,还要考虑胁迫的时间效应,从而平衡植物“产量”与“质量”的最佳方案. | 朱丹 赵宝林 韩科学 赵晓 | 2020 | 北京师范大学学报(自然科学版)2020，56，4： | 4 |

| 16 | Molecular functions of nitric oxide and its potential applications in horticultural crops显示文摘Nitric oxide(NO)regulates plant growth,enhances nutrient uptake,and activates disease and stress tolerance mechanisms in most plants,making NO a potential tool for use in improving the yield and quality of horticultural crop species.Although the use of NO in horticulture is still in its infancy,research on NO in model plant species has provided an abundance of valuable information on horticultural crop species.Emerging evidence implies that the bioactivity of NO can occur through many potential mechanisms but occurs mainly through S-nitrosation,the covalent and reversible attachment of NO to cysteine thiol.In this context,NO signaling specifically affects crop development,immunity,and environmental interactions.Moreover,NO can act as a fumigant against a wide range of postharvest diseases and pests.However,for effective use of NO in horticulture,both understanding and exploring the biological significance and potential mechanisms of NO in horticultural crop species are critical.This review provides a picture of our current understanding of how NO is synthesized and transduced in plants,and particular attention is given to the significance of NO in breaking seed dormancy,balancing root growth and development,enhancing nutrient acquisition,mediating stress responses,and guaranteeing food safety for horticultural production. | Chengliang Sun Yuxue Zhang Lijuan Liu Xiaoxia Liu Baohai Li Chongwei Jin Xianyong Lin | 2021 | Horticulture Research2021，8，1： | 2 |

| 18 | Arabidopsis U-box E3 ubiquitin ligase PUB11 negatively regulates drought tolerance by degrading the receptor-like protein kinases LRR1 and KIN7显示文摘Both plant receptor-like protein kinases(RLKs)and ubiquitin-mediated proteolysis play crucial roles in plant responses to drought stress.However,the mechanism by which E3 ubiquitin ligases modulate RLKs is poorly understood.In this study,we showed that Arabidopsis PLANT U-BOX PROTEIN 11(PUB11),an E3 ubiquitin ligase,negatively regulates abscisic acid(ABA)-mediated drought responses.PUB11 interacts with and ubiquitinates two receptor-like protein kinases,LEUCINE RICH REPEAT PROTEIN 1(LRR1)and KINASE 7(KIN7),and mediates their degradation during plant responses to drought stress in vitro and in vivo.pub11 mutants were more tolerant,whereas Irr1 and kin7 mutants were more sensitive,to drought stress than the wild type.Genetic analyses show that the pub11 Irr1 kin7 triple mutant exhibited similar drought sensitivity as the Irr1 kin7 double mutant,placing PUB11 upstream of the two RLKs.Abscisic acid and drought treatment promoted the accumulation of PUB11,which likely accelerates LRR1 and KIN7 degradation.Together,our results reveal that PUB11 negatively regulates plant responses to drought stress by destabilizing the LRR1 and KIN7 RLKs. | Xuexue Chen Tingting Wang Amin Ur Rehman Yu Wang Junsheng Qi Zhen Li Chunpeng Song Baoshan Wang Shuhua Yang Zhizhong Gong | 2021 | Journal of Integrative Plant Biology2021，63，3： | 2 |
| 19 | Transcriptomic and metabolomic analyses reveal that exogenous strigolactones alleviate the response of melon root to cadmium stress显示文摘Strigolactones(SLs)are classified into plant hormones,playing a key role as a mediator of plant growth in response to several abiotic stresses.Cadmium(Cd),a common heavy metal and soil pollutant,can suppress plant growth and development.In this work,we explored the effects of exogenous SLs on root formation in response to Cd stress using melon seeds subjected to seven germination treatments:CK(control),Cd(300 μmol·L^(-1) CdCl_(2)),and SL1-SL5(CdCl_(2)-stressed seeds pretreated with 0.1,0.5,1,2,and 3 μmol·L^(-1) GR24 solutions).The results indicated that SLs increased the antioxidant enzyme activities and root vigor and decreased the malondialdehyde(MDA)contents in the roots of Cdstressed melon seedlings.Then we used transcriptomic and metabolomic analyses to explore the mechanisms by which exogenous SLs protect against Cd stress.There were 242 significant differentially expressed genes(DEGs)(78 upregulated,164 downregulated)and 247 significantly differentially expressed metabolites(DEMs)(222 upregulated,25 downregulated)between the Cd and SL3 treatments.SLs altered the expression of genes related to redox formation processes,including peroxidase(POD),lipoxygenase(LOX),glutamate dehydrogenase(GDH),and glutathione S-transferase(GST).In addition,we found that SLs regulated the expression of the MYB,AP2/ERF,bHLH,and WRKY transcription factor families.The combined transcriptomic and metabolomic analyses revealed that the DEGs and DEMs involved in Cd stress alleviation were mainly related to the gene expression of jasmonic acid(JA)and flavonoid biosynthesis.SLs might induce LOX-related genes to regulate JA biosynthesis.Moreover,SLs might promote flavonoid biosynthesis by regulating eleven flavonoid-related genes and eight metabolites.The results provide a new perspective for studying the adaptation of plants to Cd stress. | Xuemiao Chen Xueyin Shi Qing Ai Jinying Han Huaisong Wang Qiushi Fu | 2022 | Horticultural Plant Journal2022，8，5： | 2 |
| 20 | 参与辣椒素合成的DnaJ基因家族全表达谱分析显示文摘背景:DnaJ蛋白在植物发育和胁迫反应中发挥重要作用。近年来,通过对辣椒基因组全面的生信分析鉴定到76个DnaJ基因。但目前尚无辣椒DnaJ基因系统发育关系和表达谱的研究报道。因此,我们对不同组织、非生物胁迫和激素响应下辣椒DnaJ基因的系统发育关系和表达谱进行了系统的分析。结果:系统发育分析显示,辣椒DnaJ基因按序列同源性可分为7个亚族(Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ和Ⅶ亚族)。辣椒DnaJ基因在不同组织中的表达显示,38%(29/76)的辣椒DnaJ基因在至少一个组织中表达。结果表明,DnaJ基因在辣椒生长发育中具有潜在的关键作用。另外,为了解辛辣和非辛辣辣椒DnaJ基因在胎座中的表达差异,我们还利用RNA-Seq数据和qRT-PCR分析了辣椒DnaJ基因的表达模式。通过比较分析发现,8个基因在辛辣辣椒和非辛辣辣椒中的表达差异显著。CaDnaJs与胎座发育过程中参与辣椒素合成的基因共同表达。更重要的是,我们的研究揭示了这8个DnaJ基因可能受到胁迫(热、干旱和盐)的调控,同时也受到植物激素的调控(ABA,GA3,MeJA和SA)。结论:综上所述,部分在胎座中表达的DnaJ基因可能参与了植物在与刺激性相关化合物生物合成过程中对非生物胁迫的响应。本研究为辣椒DanJ基因的表达谱提供了广泛的认识,有助于我们对辣椒中的DnaJ基因功能认识。 | Fang Fanfei Liu Fawan Yang Xian Wan Hongjian Kang Yunyan 刘周斌(译) | 2020 | 辣椒杂志2020，，3： | 2 |
